3
Turn the ignition off.
Disconnect the TP Sensor harness connector.
With the DRBIII
t, monitor the TP Sensor voltage.
Ignition on, engine not running.
Is the voltage above 4.5 volts?
All
Yes
→ Replace the Throttle Position Sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 4
4
Turn the ignition off.
Disconnect the TP harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K22) TP Signal circuit at the TP
Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes
→ Repair the short to ground in the (K22) TP Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 5
5
Turn the ignition off.
Disconnect the TP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K22) TPS Signal circuit and the (K4) Sensor
ground circuit in the TPS harness connector.
Is the resistance below 100 ohms?
All
Yes
→ Repair the short to (K4) Sensor ground in the (K22) TP Signal
circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 6
6
NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.
